Abstract (en)

[origin: US2016029434A1] Provided are a method and apparatus for calculating a paging occasion under an extended paging cycle. The method includes: calculating a frame number (SFN) where a paging message occurs by user equipment (UE) by using a formula SFN mod T=(T div N)*(UE_IDextended mod N); calculating a subframe number (i_s) where the paging message occurs by the UE by using a formula i_s=floor (UE_IDextended/N)mod Ns; and determining by the UE a paging occasion of the UE under an extended paging cycle by using the frame number and the subframe number where the paging message occurs; where, T is a paging cycle of the UE, which is equal to a specific discontinuous reception (DRX) value of the UE; UE_IDextended=IMSI mod (1024·2n), UE_IDextended being an identity index of the UE, IMSI is an international mobile subscriber identity of the UE, and n is the number of bits of an extended SFN; N=min(T,nB); Ns=max(1,nB/T); and nB∈{4T,2T,T,T/2,T/4,T/8,T/16,T/32}.
